Hello, I attached the dmesg log I got after recovering from a suspend-to-disk. At the beginning there is a strange behaviour that then led to a device reset (as far as i understood) and immediately after I hit a warning in iwl-trans.h.. I am running linux-3.5.1 and this is the device I am using: 02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 (rev 34) I can test whatever patch, if needed. Cheers, -- Antonio Quartulli ..each of us alone is worth nothing.. Ernesto "Che" Guevara
